Hello datum1m and nath

Welcome to the ODK forums.
I'm no expert on these boxes but this post appears to be a good one for
diagnosis. So, the pulley was hot because of the bearing failures.
It may be - probably - that the bearings failed because the belt tension
was too great on the input pulley over a period of time.

To answer your question, a bearing supplier should stock imperial sizes.
Normally, the bearing casing will have an identifier number.
Given that the parts lists only shows 2 bearings, that would be correct (not three)
It is normal practice to separate them - probably for heat dissipation.

Thanks to nath for his knowledge here: Much appreciated.

Please let us know how you go.
